10-24mm is a Great lens. Its not cheap. Most expensive lens I've bought so far. But worth every penny. Great Contrast and sharpness. The photo show was taken using it. I had to perspective correction in Lightroom 4 because I was at a position below the church.
Other pictures that were shot straight on I didn't have to do anything. (They are in the same album as the one I posted) all the ones which have the excellent focus and sharpness and contrast were taken with this lens. The others with the Focus not as sharp and sort of bright are taken with another lens.
As for myself I'm sure the the 5100/5200 is a Great camera. But I see the articulating LCD screen as being something more delicate and more apt to damage. or to go bad. With all the wires going from camera to screen, having to flex and twist. As Former Electronics Technician. Anything that has flex an twist is more like to need period repair.
